Combatting stunting: The vital role of animal protein in early childhood nutrition

Stunting is a global issue that significantly affects the quality of human resources and a nation's future competitiveness. Therefore, this study aimed to explore the role of animal protein in preventing stunting in early childhood using an exploratory approach. The procedures were carried out using a qualitative descriptive design by conducting a literature review and collecting secondary data. The results showed that animal foods (eggs, milk, and meat) contained bioactive compounds and essential amino acid profiles (valine, leucine, isoleucine, phenylalanine, tryptophan, lysine, histidine, methionine, and threonine), indicating the ability to provide the required nutrients and prevent stunting. In addition, optimizing nutrition in the first 1000 days of life starting from the conception phase until the age of 2 years by consuming a variety of nutritious foods containing animal protein at every meal was expected to prevent the condition. The results also revealed that providing sufficient animal foods that were physically and economically accessible to all individuals in society was a major challenge. Therefore, efforts were needed from the government to realize the goal of reducing stunting in Indonesia. Keywords: Stunting, Early Childhood, Animal Foods, Protein

How wealthy in natural resource leads environmental sustainability in developing economies? An empirical investigation

This study investigates the impact of income generated from natural resources on environmental sustainability and analyses the moderating role of institutional quality in carbon emissions function. An extensive dataset from 61 developing nations covering the years 2000–2018 has been taken, which uses a dynamic heterogeneous panel data model. Our study follows a rigorous methodology by applying the pooled mean group estimator. An extensive examination of the impacts over the short run and long run is possible using this method. This study reveals multifaceted findings: in the short run, the effect of institutional quality and natural resources revenues on carbon emissions is insignificant, implying that such factors have a relatively minor impact. The long-term examination reveals that income derived from natural resources causes a spike in carbon emissions, which causes environmental deterioration and climate change. Strong institutional quality can significantly mitigate the adverse effects of correlation between revenues from natural resources and carbon emissions, which have been observed. The study's moderating effect of natural resources richness, which gradually reduces institutional quality's ability to reduce carbon emissions, is a crucial finding. Our study significantly advances the field of environmental economics, especially when discussing sustainable development in emerging nations with abundant natural resources. It emphasizes the delicate balance that must be struck between preserving efficient environmental governance and maximizing the richness of natural resources. Our findings underscore the crucial need for developing nations to strengthen their institutional frameworks and capacities and have substantial policy implications. These steps are essential to ensuring that the use of natural resources is in line with environmental sustainability objectives, turning resource curses into blessings for long-term development and environmental preservation. This research opens the door to sector-specific impacts and personalized policy interventions in resource-rich developing economies.

Abstract B025: Assessing the content and quality of online patient education material on clinical trials from NCI-designated comprehensive cancer centers

Abstract Background: Online patient educational material on cancer clinical trials is available on NCI- designated comprehensive cancer center websites and official YouTube channels. Online health information is an important resource for patients seeking to learn more about treatment options. Objective: Examine the quality and content themes in online patient educational material (PEM) related to cancer clinical trials published by comprehensive cancer centers. Methods: A random sample of comprehensive cancer centers (21) was chosen to represent the national network of cancer centers. Each website was searched for webpages containing patient-oriented clinical trial information. Official YouTube channels were also searched for relevant video material. Each webpage and video (N=196) were assessed for quality and content themes. Quality was measured using an abbreviated Patient Education Materials Assessment Tool which scores understandability and actionability of text and audio-visual materials, and content themes were assessed by the use of a content characteristic codebook. Results: Common content themes in the sample (N=196) of online PEM from comprehensive cancer centers were defines purpose of trials, physician speaker, animated or illustrated elements, and defines phases of trials. Online PEM had an average score of 83 for understandability and 26 for actionability, an area for improvement. Only 10% of materials reviewed scored high for understandability (>90) and for actionability (>70). Online webpages that mixed text and video scored highest on the quality assessment. Video-only content scored lowest on the quality assessment. Only a small percentage of PEM included FAQs (10%), instructions on how to find a trial (16%), mentioned consent (14%) or costs associated with trials (12%). Mentions or depictions of minority populations were not commonly observed in the material (11%). Conclusions: Online PEM published by comprehensive cancer centers is an important and easily accessible resource for patients looking to learn more about clinical trials. Cancer centers should add various audio-visual formats and interactive tools to their webpages to increase the quality of the clinical trial resources. Including representation of historically underserved populations and adding actionable advice for patients has the potential to engage patients’ interest and increase enrollment in cancer clinical trials.

The training was provided to 50 participants from the Family Welfare Empowerment (PKK) of Cibodas Village, resulting in the creation of village flagship products. Through this training, participants will become catalysts, spreading information to raise awareness in the community and improve continuous education to achieve greater well-being and quality of life.

Variable juvenile growth rates and offspring size: a response to anthropogenic shifts in prey size among populations.

Environmental variables, such as resource quality, shape growth in organisms, dictating body size, an important correlate of fitness. Variation in prey characteristics among populations is frequently associated with similar variation in predator body sizes. Anthropogenic alterations to prey landscapes impose novel ecological pressures on predators that may shift predator phenotypes. Research has focused on determining the adaptability of the phenotypic response by testing its genetic heritability. Here, we asked if anthropogenic shifts in prey size across the landscape correlate with juvenile growth rates among populations of watersnakes with divergent life-history phenotypes. We sought to determine if growth rate variation is the product of genetic adaptation or a non-heritable phenotypic response. Using a common-garden design, we measured growth of neonate snakes from fish farms varying in prey size. We found juvenile growth rates are faster for snakes with larger initial body sizes and from populations with larger average prey sizes. Our data suggest variability in juvenile grow rates within and among populations are not the product of genetic adaptation, but the indirect consequence of initial offspring size variation and prey consumption. We propose larger offspring sizes may favor increased juvenile growth rates, mediated through a larger morphological capacity to consume and process energy resources relative to smaller individuals. This experiment provides evidence supporting the growing body of literature that non-heritable responses may be significant drivers of rapid phenotypic divergence among populations across a landscape. This mechanism may explain the stability and colonization of populations in response to rapid, human-mediated, landscape changes.

Advances and Challenges in Pest Management for Protected Cultivation in India: Integrative Approaches and Future Prospects

Poly house farming in India has transformed agriculture by enabling year-round crop production and protecting crops from adverse weather. However, the controlled environment of poly houses represents unique challenges in pest management, making it crucial to implement effective strategies to maintain crop health and yield. Integrated Pest Management (IPM) offers a comprehensive approach that combines cultural, biological and chemical practices to control pests while minimizing environmental impact. The advantages of protected cultivation include increased productivity, improved produce quality and efficient resource utilization. Despite these benefits, poly house farming faces limitations such as high initial costs, the need for meticulous planning and ongoing crop protection requirements. Pest identification is vital for effective management, as misidentification can lead to inappropriate control measures. Common pests in poly houses include insects, slugs, mites, nematodes, pathogens and weeds. Pest monitoring strategies such as scouting, using monitoring tools and record-keeping are essential for timely and effective management interventions. Management strategies encompass physical, biological and chemical methods. Physical approaches include the use of sticky and pheromone traps, while biological control involves the release of natural predators and entomopathogens. Chemical management involves both biorational pesticides and conventional chemicals, with IPM emphasizing the integration of these methods to reduce reliance on harmful chemicals. Preventive measures like insect-proof screens and soil solarization, along with curative measures and advanced technologies like video camera networks and decision support systems, are pivotal for effective pest control. Future prospects include improving technology standards, enhancing computerized control systems, and fostering research and government support to advance protected cultivation in India.

Active pharmaceutical contaminants in drinking water: myth or fact?

Global water availability has been affected by a variety of factors, including climate change, water pollution, urbanization, and population growth. These issues have been particularly acute in many parts of the world, where access to clean water remains a significant challenge. In this context, preserving existing water bodies is a critical priority. Numerous studies have demonstrated the inadequacy of conventional water treatment processes in removing active pharmaceutical ingredients (APIs) from the water. These pharmaceutical active compounds have been detected in treated wastewater, groundwater, and even drinking water sources. The presence of APIs in water resources poses a significant threat not only to aquatic organisms but also to human health. These emerging contaminants have the potential to disrupt endocrine systems, promote the development of antibiotic-resistant bacteria, and bioaccumulate in the food chain, ultimately leading to unacceptable risks to public health. The inability of current conventional treatment methods to effectively remove APIs from water has raised serious concerns about the safety and reliability of water supplies. This issue requires immediate attention and the development of more effective treatment technologies to safeguard the quality of water resources and protect both aquatic ecosystems and human health. Other treatment methods, such as nanotechnology, microalgal treatment, and reverse osmosis, are promising in addressing the issue of API contamination in water resources. These innovative approaches have demonstrated higher removal efficiencies for a wide range of APIs compared to conventional methods, such as activated sludge and chlorination, which have been found to be inadequate in the removal of these emerging contaminants. The potential of these alternative treatment technologies to serve as effective tertiary treatment. To address this critical challenge, governments and policymakers should prioritize investment in research and development to establish effective and scalable solutions for eliminating APIs from various water sources. This should include comprehensive studies to assess the performance, cost-effectiveness, and environmental sustainability of emerging treatment technologies. The emerging contaminants should be included in robust water quality monitoring programs (Aus der Beek et al. in Environ Toxicol Chem 2016;35(4):823-835), with strict regulatory limits enforced to protect public health and the environment. By doing so, the scientific community and regulatory authorities can work together to develop a multi-barrier approach to safeguarding the water resources and ensuring access to safe, clean water for all. This review explores the potential of alternative treatment technologies to serve as viable solutions in the fight against API contamination. Innovative approaches, including nanotechnology, microalgal treatment, and reverse osmosis, have demonstrated remarkable success in addressing this challenge, exhibiting higher removal efficiencies compared to traditional methods.

Escalation of Human Resource Quality in National Health Resilience Through Estimating Multilevel Model Parameters with the Restricted Maximum Likelihood Approach to The 2019 UTBK Average

Multilevel modeling or Hierarchical Linear Modeling (HLM) is a statistical approach specifically used to analyze data with a two-level structure. This approach allows an understanding of the contribution of factors at both the individual and group levels to the response variable. One method commonly used in HLM is Restricted Maximum Likelihood (REML). REML is a parameter estimation method that is often applied in statistical models, especially linear models that incorporate random components. This allows more efficient parameter assessment compared to conventional estimation methods. In this research, multilevel model parameter estimation analysis was carried out using the limited maximum likelihood approach. The aim is to determine the multilevel linear regression model on the average UTBK score for health cluster study programs in 2019. This involves selecting the optimal node point based on the minimum Generalized Cross Validation (GCV) and identifying the factors that influence it. Predictor variables considered include interest and capacity of study programs at university level (Level-1), as well as the average UNBK and HDI scores at provincial level (Level-2). The findings of this research indicate that the most appropriate multilevel regression model is formed with three nodes with a minimum GCV value at Level-1 of 864.6593 and at Level-2 of 3.1816. At Level-1, the influencing factor is the interest variable and at Level-2 is the average provincial UNBK score in 2019 and the Human Development Index (HDI).

Investigation of hydrochemical characteristic, water quality and associated health risks of metals and metalloids in water resources in the vicinity of Akamkpa quarry district, southeastern, Nigeria

Quarrying of rock aggregates generates produced water that, if not handled properly will be a source of pollution for nearby water bodies, thus affecting the chemistry of the water. This study examined the chemistry, impact of quarrying activities on water resources and the health consequences/risks posed by ingestion of the water by humans in the Akamkpa quarry region in southeastern Nigeria. Thirty (30) water samples consisting of pond water, stream water, hand dug wells, and borehole samples were collected and analyzed for their physicochemical parameters using standard methods. The results obtained from the analyses indicated that the water was moderately acidic, fresh, and not salty, with many parameters below the recommended standards with Ca2+, and HCO3− being the dominant ions present in the water resources. Rock weathering processes including silicate weathering as illustrated by hydrochemical facies, cross plots, and Gibbs diagrams are the dominant mechanisms influencing the quality and major ions chemistry of the water resources with minor contributions from dissolution, anthropogenic activities, and ion exchange. Ca-Mg-SO4-Cl and Na–K-HCO3− are the most important water types. Although the water quality index shows that the water is suitable for human use and irrigation, the mean values of As, Cd, Pb, and Se are above the acceptable limits. Additionally, the calculated contamination factor revealed the water resources are moderate to highly contaminated by As, Cd, Cr, Mo, Pb, Sb, and Se, and are therefore unsuitable for consumption with regards to these parameters. However, the residual sodium carbonate and water hazard index (WHI) values showed that 38% to 90% of sites in the quarry area were unsuitable for cultivation, 10–30% were in the low to medium impact category, and 60% were classified as risky and are from high to very high impact category. A non-cancer study of inhabitants living in the vicinity of the quarry area indicated that 6.7% of the sites have values greater than one, indicating that it may endanger the health of the people. Therefore, constant monitoring of the water quality is recommended as long-term use of contaminated water can harm humans, plants, and soils.

This article reviews the innovative digital tools and strategies adopted during this period, such as microlearning, virtual reality, and tablet apps, which were central in maintaining educational quality. While online platforms offered flexibility, accessibility, and global reach, challenges such as the lack of personal interaction and variability in resource quality persisted. The article emphasizes the importance of balancing online and in-person learning and highlights future directions in radiology education, including the integration of Artificial Intelligence (AI) and Virtual Reality (VR) to enhance training. By leveraging these advancements, radiology education can continue to evolve, offering comprehensive and adaptable learning experiences for trainees.

Nutritional Quality of Basal Resource in Stream Food Webs Increased with Light Reduction—Implications for Riparian Revegetation

Biofilms are considered a basal resource with high nutritional quality in stream food webs, as periphytic algae are abundant of polyunsaturated fatty acids (PUFAs). PUFAs are essential for growth and reproduction of consumers who cannot or have very limited capacity to biosynthesize. Yet, how the nutritional quality based on PUFA of basal food sources changes with light intensity remains unclear. We conducted a manipulative experiment in mesocosms to explore the response and mechanisms of nutritional quality to shading, simulating riparian restoration. We found a significant increase in PUFA% (including arachidonic acid, ARA) under shading conditions. The increased PUFA is caused by the algal community succession from Cyanobacteria and Chlorophyta to Bacillariophyta which is abundant of PUFA (especially eicosapentaenoic acid, EPA; docosahexaenoic acid, DHA). On the other hand, shading increased PUFA via upregulating enzymes such as Δ12 desaturase (FAD2, EC:1.14.19.6) and 3-ketoacyl-CoA synthase (KCS, EC:2.3.1.199) in the biosynthesis of unsaturated fatty acid elongation pathways. Our findings imply that riparian reforestation by decreasing light intensity increases the nutritional quality of basal resources in streams, which may enhance transfer of good quality carbon to consumers in higher trophic levels through bottom-up effects.

The importance of institutional capacity in drinking water supply system governance: A policy evaluation from border area

In most developing countries, the equal access to clean and potable water is a major challenge faced by many communities. This research aims to evaluate water supply system governance policies as well as potential springs, constraints and problems related to the water needs of border communities. This research is a descriptive study using a qualitative approach. The qualitative approach looks at policies, institutions, conflicts, and problems faced, as well as looking at data on water sources, socio-economic challenges, culture, and local wisdom. The research location was in Belu Regency, on the Indonesia-Leste Timor border. Research informants were representatives of local government, academics and the community. The problems faced are the underdevelopment of piped networks due to budget constraints, low capacity and quality of human resources, and the absence of specific regulations governing the Drinking Water Supply System (SPAM). The study area has springs spread across 11 subdistricts, with raw water potential ranging from 0.5 to 250 liters per second. Most of these water sources are good for community consumption, but some have not been optimally utilized so that they cannot be fully utilized to meet the needs of the population. The results show that SPAM management policies can be implemented to a certain extent, but have not yet run optimally because they still require capacity building and competence of the apparatus and local communities and an increase in the role of local governments to help implement central government policies in relation to assistance tasks and as a tool for deconcentration of the central government. In conclusion, the potential of raw water sources has not been fully utilized due to the challenges of infrastructure development and the limited capacity of human resources and budgets. Without good management and institutional support, communities will continue to face problems related to access to clean water.

Implementing falls prevention patient education in hospitals - older people’s views on barriers and enablers

BackgroundWorld falls guidelines recommend that hospitalised older patients receive individualised falls prevention education, yet no studies have sought older people’s feedback on how best to deliver falls prevention education in hospitals. The objective of the study was to explore the perspectives of older people and their caregivers about barriers and enablers to implementation of a tailored hospital falls education program.MethodsA qualitative descriptive design was used. Three focus groups and 16 semi-structured interviews were conducted. A purposive sample of older people who had previous hospital admissions and caregivers of older people were selected to review a co-designed patient falls education program (the revised Safe Recovery program). They provided feedback on how to implement the program in hospital settings. Data were thematically analysed taking an deductive-inductive approach.ResultsParticipants were 37 older people [female n = 24 (64.9%), age range 64 to 89 years] and nine caregivers (female n = 8). The first theme was that the Safe Recovery Program resources were of high quality, enabling strong patient engagement and increased knowledge and awareness about falls prevention in hospitals. The second theme identified practical strategies to enable program delivery in hospital wards. The key enablers identified were: timing of delivery around wellness and the patient’s mobility; tailoring messages for each older patient; key staff members being assigned to lead program delivery. Participants recommended that staff assist older patients to set appropriate behavioural goals in relation to preventing falls in hospitals. They also recommended that staff raise older patients’ confidence and motivation to take action to reduce the risk of falls. Providing resources in other languages and alternative shorter versions was recommended to enable broad dissemination.ConclusionsOlder people and their caregivers advised that implementing falls education in hospitals can be enabled by using high quality resources, delivering falls education in a timely manner and personalising the education and support to individual needs.

Elemental composition and potential toxicity of the riverine macrophyte Podostemum ceratophyllum Michx. reflects land use in eastern North America

Land use influences surface water quality, often alleviating stoichiometric constraints on primary production and altering biogeochemical cycling. However, land use effects on nutrient content and potential trace metal accumulation in aquatic plants remain unclear, and high concentrations of metals and altered nutrient ratios could impact the health of herbivores and detritivores. We tested for land use effects on nutrient and trace metal accumulation in a widespread riverine macrophyte, Podostemum ceratophyllum, collected from 91 locations from Georgia to Maine, USA in 2014–2016. We quantified carbon (C), nitrogen (N), phosphorus (P), their molar and mass ratios, N and C stable isotopes, and 17 additional elements in dried plants collected from each location to estimate relationships between plant tissue content and watershed land use, which we quantified as agriculture, forest, and development. Decreasing forest cover was correlated with increasing δ15N, Mg, Mn, and P in Podostemum tissue. Increasing urban development was correlated with increasing δ15N, Mg and P, while increasing agriculture was correlated with a decrease in C: P and the concentrations of multiple metals, along with increases in P, Mg and δ15N. Decreases in ratios of N: P and C:P with increasing agriculture and urban development in the watershed indicate more rapid P storage relative to C and N in plant tissue, and increased resource quality of the plant to consumers in these watersheds. We also observed potentially toxic dietary concentrations of some trace metals (B, Cd, Tl, Zn) in plant tissue which could be related to the plant's natural herbivory defense system or to land use. We conclude that land use influences the elemental composition of P. ceratophyllum, and potentially the quality and toxicity of the plant to herbivores and detritivores in eastern North American rivers.

The influence of human resource quality and superiors support on the usability of the accounting and management information system of state-owned asset

This study aims to investigate the influence of human resource quality and superior support on the effectiveness of the Accounting and Management Information System for State-Owned Assets (SIMAK-BMN) at Universitas Terbuka. The study's results, which provide empirical evidence that the quality of human resources significantly and positively impacts the usability of SIMAK-BMN, as demonstrated by the t-test, are significant. Employing a quantitative research approach, the study's population comprises leaders and users of the Accounting and Management Information System for State-Owned Assets, totaling 57 respondents distributed between the Central Universitas Terbuka and various regional offices. The sampling method utilized in this research is nonprobability sampling, specifically purposive sampling, to ensure that participants possess relevant experience with the system. Primary data were collected through structured questionnaires distributed to respondents and analyzed using various statistical techniques. These included correlation analysis and multiple regression, descriptive statistics and reliability testing. To ensure the robustness of the findings, validity testing was conducted alongside classical assumption tests, encompassing multicollinearity testing, hypothesis testing, and comprehensive discussion. On the other hand, the variable of superior support does not significantly influence the use of the Accounting and Management Information System for State-Owned Assets. These findings have significant implications, suggesting that while enhancing human resource quality can improve the system's usability, efforts to bolster superiors support may yield a different level of effectiveness. The study underscores the importance of focusing on human resource development to optimize the utilization of management information systems within the academic environment.
